My understanding is that ;
on the 24 th of June 2010 , a woman in a wheel chair , accompanied by a man went to the Aust. credit Union in Elizabeth to update banking records and held a conversation with the bank . This male and wheelchair female were able to convince that Bank , that the female in the wheel chair was Karlie.
Then on the 15th of Dec 2010, a female , went to a centre link appointment at Salisbury and said that she was Karlie and also had documents for herself and Khandalyce BUT they do not know , if female is the same as the one in the wheelchair , who attended the Bank , earlier that same year . [ NO MENTION OF A WHEELCHAIR at the centrelink appointment ]
its in my opinion , that they are two different woman , that is why , in the first police interview , they said that they are possibly looking for at least 2 females .
There was a report in The Advertiser on 31 October 2015 which mentions a woman in a wheelchair at both the credit union and Centrelink.
They said a woman in a wheelchair had visited a credit union in Adelaides northern suburbs and posed as Ms Pearce-Stevenson to update her records in June 2010.
A woman in a wheelchair also had gone to Centrelink at Salisbury claiming to be Ms Pearce-Stevenson in December 2010.
